HORSESHOE.

Specification of Letters Patent.

Patented June 28, 1910.

Application filed December 30, 1909. Serial No. 535,683.

To all whom it may concern:

Be it known that I, MICHAEL D. BRILL- HART, a citizen of the UnitedStates, residing at Sterling, in the county of Wayne and State of Ohio,have invented new and useful Improvements in Horseshoes, of which thefollowing is a specification.

This invention pertains to horseshoes of the removable-call: type and itcontemplates the provision of a horseshoe embodying simple and efiicientmeans to preclude unintentional movement or displacement of a calk whilethe shoe is in use and yet adapted to permit of the ready removal of thecalk and its replacement by a new one when necessity demands.

With the foregoing and other objects in view, the invention consists inthe novel construction, combination and arrangement of partsconstituting the invention to be hereinafter specifically described andillustrated in the accompanying drawings which form a part hereofwherein is shown the preferred embodiment of the invention, but it is tobe understood that changes, variations and modifications can be resortedto which come within the scope of the claim hereunto appended.

In the drawings, in which similar reference numerals indicate like partsin the different figures: Figure 1 is a plan of the under face of ahorseshoe embodying this invention. Fig. 2 is a view in end elevation ofone of the heel portions of the horseshoe shown in Fig. 1. Fig. 3 is asectional view on line X of Fig. 1; and, Fig. 4 is a plan of a preferredform of calk detached from a horseshoe.

Referring to the drawings, the reference numeral 1 denotes a horseshoeof conventional type provided with grooves 2 in which are apertures 3for receiving the nails for securing the device to the hoof of a horse.In the toe portion of the shoe are two apertures 4 to receive nails forsecuring this portion of the shoe to the hoof. The under face of the toeportion of the shoe is provided with a transverse T-shaped groove 5 andwith the body portion 6 in advance of the groove preferablycurvilinearly-formed. The portions of one of the 'side walls of thegroove 5 on each side of the medial line thereof are at a slight obtuseangle with respect to each other, the

said angle being indicated in the drawings by the reference numeral 7.Mounted in the groove 5 is a calk 8 which is formed with a T-shapedportion 9 arranged to be received in the T-shaped groove 5. This calk 8is preferably formed with a slight obtuse angle at its central medialportion so that when driven into the groove 5 it will fit therein sosnugly as to not become accidentally or unintentionally displaced, butmay be driven therefrom by a hammer in the hands of an operator whendesired to remove the same for sharpening, or to replace the worn calkby a new one. The heel portions 10 of the shoe are each provided with alongitudinally-extending T-shaped groove 11 which is formed so that theend portions of one side edge of each of the grooves are at a slightobtuse angle with respect to each other. Mounted in each of thesegrooves 11 is a calk 12 provided with a T-shaped portion 13 to seat inits respective groove 11 and with the outer projecting portion of eachcalk formed as desired, but shown in Fig. 2 as having a sharpened outeredge 14:; however, any other form or configuration may be imparted tothe projecting portion of the calk as may be deemed best. These calks 12are preferably formed as shown in Fig. 4 with the portions on each sideof the transverse medial line thereof bent at an obtuse angle withrespect to each other so as to fit in the similarly-formed grooves 11. pThe oalks 8 and 12 are secured in position by driving them into theirrespective grooves and when so positioned they are prevented fromaccidental withdrawal by reason of the angular formation of the groovesand calks which causes an interlocking engagement between theseelements; but if necessary for any reason the calks may be removed bydriving them outwardly from the grooves. The grooves 11 and calks 12 arepreferably-so positioned in the heel portions of the shoe that theapices of the angles formed therein will be inward so as to beoppositely-disposed with respect to each other.

This invention contemplates that in the manufacture of calks they willbe rolled in approximately continuous lengths, after which theindividual calks may be severed from the stock and before insertion intothe grooves in the shoe each individual call: may

be given the angular conformation heretofore described, by the use of ahammer or other suitable tool.

I claim:

The combination with a horseshoe provided in its under face with aT-shaped recess extending from one of the lateral sides thereof into thebody of said shoe and constituting a socket for a calk, one of the sidewalls of said recess formed with an obtuse angle, of a calk comprising abar suitably fashioned to be passed into said socket from the open endthereof, the sides of said calk formed parallel and each with an obtuseangle therein whereby it will in- 15 my hand in presence of twosubscribing wit- 20 nesses.
